Abstract

PURPOSE:To display a processing time on a screen of a terminal device as a response time before execution of a command by estimating automatically the processing time of the command inputted in a command system. CONSTITUTION:When the operator inputs a command A from a terminal device 1 to a processing unit and stored tentatively in a command storage pool 21 of a command storage section 2. A command decoding section 3 refers to a command module relating table 51 in a storage device 5 to decode the command A, which is expanded into constitution modules 1, 2, 3. A processing time calculating section 10 uses a processing time calculation expression discriminated from a basic function table 52 to calculate processing times t1-t2 at each module and displays the total time T=t1+t2+t3 on the terminal device 1 as the response time of the command A. The operator observes the displayed response time and discriminates whether the command A is executed as it is or other command is to be executed earlier.

Description

[Detailed Description of the Invention] [Field of Application of the Invention] The present invention relates to a command response time estimation method, and particularly to a command response time estimation method suitable for estimating the response time in a command system having a group of highly functional commands. .

[Background of the invention]

Conventionally, for example, as a method for estimating the output time of an output file, a method is known that estimates and displays the output time of an output file, which the operator could not predict, as shown in Japanese Patent Application Laid-open No. 58-195919. There is. but,
This method can only be applied to objects such as output files whose processing time can be estimated from the processing speed of the data processing device and the number of output lines. Therefore, the target terrorist command system of the present invention, that is, a conversational processing system in which a worker inputs an instruction or command to interactively execute a desired processing function from a terminal screen and obtains a processing result immediately, can be used, for example, in a production control system. The following problems that occur when applied cannot be solved by the above method.

First, when commands are used by workers who are not familiar with computer performance or command internal procedures, it is difficult to predict the response time of input commands. However, in production management, etc., the usage methods and amount of data handled differ depending on the factory or workplace, so it is difficult for designers to take these into account when designing commands. . Second, high functionality is required for commands that can be easily used even by non-expert computer users, but if the commands are made to be highly functional, processing time will be longer and responsiveness will be lowered. Third, among the functions required for production management, etc., there are many functions for solving combinatorial problems, such as scheduling, but when such functions are converted into commands, a large amount of processing time is required due to the increase in input data for the commands. The user must sit at the terminal and wait for a response without any information.

Fourth, in command systems that have the ability to create commands for new functions by combining existing commands, there are problems such as the inability to create practical commands without carefully examining the responsiveness of each command. There is a point.

[Purpose of the invention]

An object of the present invention is to solve the above-mentioned problems of the prior art by automatically estimating the processing time of a command input in a command system so that a command response can be displayed as a response time on a terminal screen before the command is executed. To provide a time estimation method.

[Summary of the invention]

The present invention provides a command system that includes a terminal that inputs commands and displays processing results or responses, and a processing device that expands the input commands into modules and sequentially executes the modules. The coefficients of the basis function of the processing time calculation formula for estimation are estimated based on the generated data, and the processing time is estimated using the processing time calculation formula above and the module expanded at the time of command input, and the total at the time of the estimation is calculated. is displayed on the terminal as the estimated response time of the command, and when the command is executed, the execution time of each module is measured, and the error between the measured data and the estimated value is judged to be outside the allowable value, and the result is determined based on the measured data. This is a command response time estimation method that re-estimates the coefficients of the basis function of the processing time calculation formula.

[Embodiments of the invention]

An embodiment of the present invention will be described below with reference to FIGS. 1 to 3. FIG. 1 shows an overall configuration diagram of a command system showing an embodiment of the command response time estimation method according to the present invention.
This is a diagram. In Figure 1, 1 is a terminal for inputting commands for interactively executing processing functions of the command system and displaying processing results or responses on the screen; 2 is a terminal for inputting commands to the processing unit from terminal 1 of the command system; A command storage section 3 includes a command storage pool 21 for temporarily storing commands;

Next, FIGS. 3(α), 3(b), and 3(C) are the first and second . FIG. 3 is a third processing flow diagram. Figure 3 (α), (
b) The operation of FIGS. 1 and 2 will be explained using (C). First, as shown in FIG. 1K and FIG. 3 (α), before the command system starts operating, the operator enters the command name and the module group that will perform the actual processing of the command into the processing device from the terminal 1, and then registers the command via the command registration unit 6. It is registered in the command/module related table 51 of the storage device 5. Then, basis functions used to create a processing time calculation formula for estimating the actual processing time of each module are registered in the basis function table 52. Note that this processing time calculation formula is expressed as a linear combination of basis functions. For example, in FIG. 2 (α), the command/module related table 51 contains
Command A and its constituent module numbers 1.2.3 are registered in the command name numbered 1. In addition, in FIG. 2(b), the basis function table 52 includes the basis function 'e'*
nlogts, n” are registered.The operator then writes the basis function table 52 for each registered module.
The terminal 1 specifies to the processing device which linear combination of basis functions is used to express the processing time calculation formula of the module.

For example, in FIG. 2 (α), for module 1 with number 1, basis function 1. Specifies to use n, nlogn. This shows that the processing time of module 1 is expressed by the following calculation formula using coefficients α, α, and α as the function TIME of the data number (3).

All the estimation results of C@ are stored in the module 11213 of the basis function table 52 where the coefficients of the Mr basis function are stored.

Second, from Figure 3(b) 4C, when the command system is in operation, the response time of the command is estimated before the command is executed, and terminal 1! When an operator inputs a command A from the terminal 1 to the processing device for lc display, it is temporarily stored in the command storage folder 21 of the command storage section 2.

Next, the command interpreter 3 reads the command in the storage device 5.
The command A is interpreted with reference to the module relation table 51, and the command A is developed into the configuration module 1.2.3. Then, the processing time calculation unit 10 calculates the processing time calculation formula (1) determined from the basis function table 52 for the modules 1 and 2゜B developed by the command interpretation unit 3.
, +21, +31 to calculate the processing time t1+F*t3 for each module, and then display the total time r=t, +tt+t on the terminal 1 as the response time of command A. At this time, the operator can look at the displayed response time and decide whether to execute command A as is or execute another command first.

Thirdly, when the operator inputs a startup command from the terminal 1 to the processing device when executing a command as shown in FIG. is initialized to zero, and
The command execution unit 4 sequentially executes modules 1.2.3. When each module is executed, the processing time measuring section 9 works to measure the actual execution time t from the timer, and stores the measured data in the measured data area 53 of the recording device 5. In this way, after the execution of all modules is completed, the error determination unit 1
1, the processing time calculation unit 10 for each module 1, 2.3
Calculate the estimation error between the estimated value of the processing time by the processing time measurement unit 9 and the actual measurement value of the processing time by the processing time measurement unit 9, and determine whether this estimated error amount satisfies a preset tolerance range, If it is satisfied, the processing of command A is terminated, and if it is not satisfied, the message and estimated error amount are displayed on the terminal 1 along with the execution result of command A. At this time, the operator looks at the message, determines whether or not to recalculate the coefficients of the processing time calculation formula, and if necessary, instructs the processing device from the terminal 1 to input the measured data area 52. Based on the stored measured data, the sum coefficient estimator 8 uses the processing time calculation formula (11, (2+, (3
Recalculate the coefficient of 1.

As described above, according to this embodiment, an operator can check the estimated response time of a command on the terminal screen and decide whether to reduce the data scale or give priority to other commands if the response is poor. It can make decisions easier.

〔Effect of the invention〕

As described above, according to the present invention, the response time of a command can be estimated and displayed when the command is input, resulting in the following effects. First, the response time of a command input by the user can be known before the command is executed without requiring special knowledge of computers or commands. Second
By knowing the response time of an input command before execution, the user can execute, stop, or replace the command (change the data scale), or perform other tasks in the meantime. Thirdly, by estimating and displaying the response time for each command based on its input conditions,
Responsiveness can be determined directly by the user at the time of use, and functions that could not be converted into commands due to decreased responsiveness can also be converted into commands. Fourth, when adding a command to a function or creating a command with a new function by combining existing commands, the responsiveness required for the command varies depending on the usage environment, so set the function with responsiveness in mind. Even if it is difficult to do so, it can be created on the assumption that the user can know the response time when inputting a command.
